Answer:

Step-by-step explanation:
The area of a circle is given by
where
is the radius of the circle. The diameter is given as
feet, so the radius of this circle is
feet.
Plugging in our values, we get:
.
Answer:
f(g(x)) =

Step-by-step explanation:
f(x) =

g(x) = 8x - 13
f(g(x) =

Step-by-step explanation:
The standard form for a line is Ax+By=C
First, we need to find the slope, or change in y over change in x. For the first one, this is
, which is impossible to find as we cannot divide by 0, meaning that this is constant horizontally -- in this case, x=2. Thus, we have 1*x+0*y=2.
For the second one, we can find the slope by getting
. We can then take the point (3,0) (it can be any point on the line) and get our equation to be y-0 = (-2/3) (x-3). Converting this to standard form, we can expand this to get
y= (-2/3)*x +2
(-2/3)*x+1*y = 2
Answer:
$125.55
Step-by-step explanation:
All you do is multiply your earned per hour by total hours.
The GCF would be 14a, because 14a x 1 = 14a, and 14a x 2b = 28ab.
